I have problem with my Lite-On 24X and CDRWIN 4.0a too. When I submit load cue sheet and wanna get start, CDRWIN reported that my CD Writer reject the cue sheet. However, when I use my old Ricoh 7060s to do the same burn, it works! And I am quite sure that the data being burnned is the excess the capicity of the CD-R media (Totally data just 400MB) Does anyone face the same problem as me? Any advice? Thanks for your attention!
